Power Battery Echelon Utilization and Recycling Strategy for New Energy Vehicles Based on Blockchain Technology

With the increasing popularity of new energy vehicles (NEVs), a large number automotive batteries are intensively reaching their end-of-life, which brings enormous challenges to environmental protection and sustainable development. This paper establishes closed-loop supply chain (CLSC) model composed power battery manufacturer NEV retailer. The benchmark scenario CLSC members without blockchain technology is analyzed, optimal recycling strategy retailer using traceability information based on discussed. We generate our findings from three aspects, as follows: or more willing take responsibility when proportion retired that can be used in echelons relatively high. Meanwhile, cost large, both manufacturers retailers should adopt obtain greater profits. Furthermore, with improvement transmission efficiency, higher profit growth rate will achieved.
